Start by planning the order
Before selecting files, decide which document should appear first, second, and last. If the files have similar names, rename them with simple numbers such as 01-cover.pdf, 02-form.pdf, and 03-receipts.pdf.
Step-by-step merge workflow
- Place all PDFs in one folder.

Common merge mistakes
| Problem | Cause | Practical fix |
|---|---|---|
| Wrong order | Files selected in the wrong sequence. | Rename files with numbers before merging. |
| File too large | Many image-heavy PDFs were combined. | Compress large files first or upload separately if allowed. |
| Missing page | A source file was not selected. | Compare the final page count with your source files. |
| Receiver rejects file | The portal requires separate documents. | Read the upload instructions before merging. |

Frequently asked questions
Can I merge PDFs in a browser?
Yes, for simple whole-file merging. You still need to check page order and file size after download.
Can I rearrange individual pages?
This tool is focused on combining whole PDFs. Use a dedicated PDF editor if you need detailed page rearranging.
Should I compress before or after merging?
If one source PDF is very large, compress it first. If the merged file exceeds an upload limit, compress the final file and review readability.
